Given numbers are 361,660,220,550

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 361,660,220,550 is 1191300.

Find LCM of 361,660,220,550 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 5 x 11 x 361 x 3 x 1 x 5 = 1191300

Therefore, the lowest common multiple of 361,660,220,550 is 1191300.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

361 x 660 x 220 x 550 = 28829460000

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

361 : 1, 19, 361

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,660,220,550, is 1.

Now, the common factors can be found like this.

361:19x 19

660:2x 2x 3x 5x 11

220:2x 2x 5x 11

550:2x 5x 5x 11

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 5x 5x 11x 11 = 24200

Therefore, the value for common factors is 24200.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 28829460000/(1x24200)

LCM = 28829460000/24200

LCM = 1191300

Thus, we can understand that the LCM of 361,660,220,550 is 1191300.
